Microbial succession in human tissues postmortem: insights from 2bRAD-M sequencing.

ABSTRACT: Microbial communities play a crucial role in decomposition, yet their patterns in human tissues remain underexplored. Most previous research has often focused on animal models such as mice and swine, with limited studies on human samples, primarily targeting specific environments like the gut and skin. Consequently, gaps persist in understanding postmortem microbial dynamics within internal human organs. The 2bRAD-M sequencing technology offers a powerful approach for human thanatomicrobiome research, overcoming key limitations of 16S rRNA and metagenomic sequencing methods. In this study, we used 2bRAD-M to profile microbial succession across seven human tissues-heart, liver, spleen, lung, kidney, calf muscle, and gut-at various postmortem intervals (PMIs). Significant variations in micro
